'This invention relates to an apparatus for use in handling broken ore or rockin loading the same into buckets or skips to be hoisted out of amine or shaft. In carrying (LTL 2A, dropped so as to overlie the the tubular bar extends ed shank 15 which meshes with threaded sleeve 16 fixed in the tubular bar this invention into effect a horizontal post is fixed at a suitable height to the wallsrof a mine shaft or drift, and on this horizontal post is mounted an inclined member affording a slidewayup which the broken ore is drawn by a scraper and is delivered to a hinged -fiop pan, overlying an opentopped bucket or skip to be filled, and having at its bottom an opening registering withthe top of said bucket. When the latter is filled the hinged pan may be raised out of the way to permit the bucket or skip to be lifted and replaced by an empty bucket or skip, and the hinged pan is then again empty bucket, all as will be hereinafter more fully set forth. i

In the accompanying drawings Fig. l is a plan view of an apparatus constructed in 2m, accordance with the present invention; Fig.

2 is a side view showing the invention in operative relation to a pile of broken ore to be loaded; Figs. 3 and 4 are plan and side views, respectively, of the loading apparatus; Figs.

A 5 and 6 are detail views of the loading scraper, Fig. 7 is a detail view of a horizontal post or v bar to be fixed to the walls of the drift or shaft and by which the loading'- apparatus is supported. f Figs. 8 and 9 are detail views of the end heads of said post or bar.

Referring to the drawings, 12 denotes a tubular post or bar to be fixed to the side walls of a mine shaft at a lsuitable height above the top of a bucket to be loaded with broken ore. This post or bar is provided at its opposite ends with enlarged parts or heads 13 and 13a having roughened or toothed outer surfaces for gripping engagement with the walls of the sha-ft. The head 13 is .provided with a shank 13b through which end a rivet 13' by which said head is xed to said bar. The head 13a is swivelled on a rivet or stud 14h integral with a block 14 provided with a screwthreadan vinternally denotedl by dotted lines in Fig. 2 when 'the scraper is a pull rope 30 passing over a snatch is a tailV rope 35 passingover a snatch block 12'lwith a shrunk fit. Fixed to the end of Y the bar 12 is a reinforcing collar 17 ,to keep.

the' said "bar: from" splitting, land fitting against the" end of saidbar 12 andthe sleeve 17 is a jack nut 16aintegral with the inter-V 55 nallythreaded sleeve 16. The head 14 is provided with openings-14Ov at right angles to each other and vinto which openingsV a suitable tool may be inserted for 'turning said head and its screw shank in the sleeve 60' l 16 to lengthen or shorten the bar 12, by virtue ofthe telescoping construction affordedby said screw shank 15 andsaid sleeve 16.

Y Fixed to the bar or post 12 is 'an'outwardly' Haring slide or guidewav 18 which may bel 652 secured in y'working position' on said baror `post bythe `clamping blocks 19 and 2O embracing said bar or post and which may be tightened and held in'place by the nuts21 on the bolts 22 passingthrough said blocks. 70d

'When the said nuts 21 are loosened the slide or guideway 18 may be adjusted to varyits inclinationor toshift it laterally on the saidf post or bar 12. The slide or guideway 18, which may be made of half-inch iron: plate, is provided with side flangesV 18a and withv a removable'wear plate 18b preferably ofi/L` inch iron plate'. Y w Mounted near the top of the-slide 'or guide- Y way`18 is a bar 23 on which is Vhinged a flop pan 24, said fioppan havingv side plates 25 embracing said bar 23.' l r[.he pan 24- isxconstructed with alarge opening 26 which, when said pan is in working position,'will be in register with an open-topped'bucket 27'when said bucket is to berloaded with ore. The pan 24 is preferably 'provided' with handles 28 byv whichV it may be lifted to the position loaded bucket 27 is tobe removed to be're- 0' placed by an emptyrbucket. i i p -The loading opera-tion will be performed Y means of a heavily weighted scraper 291 which will engage a pile of broken ore as denoted in` Fig.V V2. Connected with said block 31l and sheave '32to'adrum 33 mounted on a platforml 34 above the apparatus d'escribed. Also connected with said scraper of ore will be drawn up said guidewayand be delivered to the pan 24 and thence to thel bucket 27. The pan 24 is provided with arms 24a which rest on the top of the bucket `27 when said pan is in operative position. To prevent the scraper from catching on the lower end of said guideway said ,lower end is preferably turned down as denoted at 182,

The scraper will then be drawn back to the pile of'ore by the tail rope 35 on the reverse rotation of the drum 33, these operations being continued until the bucket is loaded. The pan 24 will then be raised to enable the loaded bucket to be hoisted out of the mine.

When the ore within the path of the scraper has been removed the nuts 21 may be loosened and the scraper be adjusted laterally on they bar or post 12 to bring it into proper opera- Y tive relation to the pile of lore to make a com' plete clean-up of all the broken rock or ore at the bottom of the shaft. By varying thel inclination of the slide orguideway 18 its lower edge 18V may always rest on the broken rock at the shaft bottom.

To get the broken ore or rock which lies under the bucket, skip or other receptacle and slideway into a position from which it can be scraped into the bucketl or skip the slideway and bar or post are removed from the shaft, ropes are then reversed on the scraper and the broken ore or rock is scraped from under the bucket or skip and piled up in the opposite end of the shaft. Then the post and slideway are put in place, the pull ropes reversed back to normal, and the broken Vore or rock scraped up the slideway.V

The snatch blocks 3l and 36, over which the pull rope 30 and tail ropes 35 run, are anchored by being connected byv chains 38 with eye-bolts 39 which are wedged into the wallsof the drift or shaft, or these eye-bolts may be fixed in any other suitable manner. Fromthe foregoing it will be understood that broken ore may be rapidly and conveniently handled in loadingk same into buckets,

above described.

Having thus described my invention. I claim and desire to secure by Letters Patent:-

l. An ore loading apparatus for mines or shafts comprising an eXtensible and contractible post or bar to be fixed tothe sides of by the mucking operation of the scraper, as

or slide adjustably mounted on said bar or post, a hinged, open-bottomed receiving pan open to said guideway, a weighted scraper constructed to drag broken ore from a pile up saidl guideway to said pan for delivery to an ore-receiving bucketv or skip, and means for y'Inovingrsaid 4scraper to. and fro in a loading operation. I i Y w2. An ore loading apparatus for mines or shafts, comprising an eXtensible and cont'ractible postor lbar to be fixed to the sides of a mine shaftIV or drift, an inclined guideway ori'slide'a'dj'ustably mounted on said Y bail or post, a hinged, open-bottomed receiving panopen to saidguideway, a weighted scraper constructed to drag broken ore from ka. pile up said guideway tosaid pan for' delivery toan ore-receiving bucket or. skip, and means for moving said scraper to and fro in a loading operation, said moving means .for said scraper comprising a double drum, pull and 'tail ropes connected to said scraper, snatch blocks and sheaves over which said ropesrun, and anchoring means for said snatch blocks and sheaves.

In testimony whereof I aHiX my signature.
